Popis:	On heating with zinc in acetic acid 2-(N-arylamino)chromone-3-carbaldehydes produce 2-(N-arylamino)-3-methylchromones, whereas 2-(N-alkylamino)chromone-3-carbaldehydes produce 4-hydroxy-3-methylcoumarin in moderate yields. Reduction of an aldehyde function to a methyl group has been achieved under very mild reaction conditions.
